Talking to the Mail on Sunday, the Prince said "there was a time I felt I wanted out". He then opened up about his decade in the army when he felt at ease, and his resentment when he was removed from the front line because his presence there was leaked by the press.

Referring to the monarchy as 'The Firm' he added, "But then I decided to stay in [The Firm] and work out a role for myself". He said his grandmother, the Queen, helped him to continue his royal duties and find the right path.

Harry also revealed he had come close to several breakdowns due to being in the public eye, but decided to take inspiration from his late mother and use his high profile status to raise awareness of various important social issues including mental health.

The charities he and his brother had chosen to support were considered very carefully, he said, "because they are on the path shown to me by our mother".

"We don’t want to be just a bunch of celebrities but instead use our role for good", he added.

Princess Diana was an advocate for many causes. She helped break down the stigma of HIV in the early '90s by holding a dying AIDs victim's hand at a time when many believed the disease could be transferred by touch, and brought the plight of land mine victims to the world's attention by walking through an active mine field in civil war torn Angola.

Harry also said the younger royals had a responsibility to modernise the monarchy as they step in to the Queen's shoes.

"We want to make sure the monarchy lasts and are passionate about what it stands for", he said.

"But it can’t go on as it has done under the Queen. There will be changes and pressure to get them right".

And, in his downtime, the Prince revealed he really is just like the rest of us — tuning in to royal drama, The Crown on Netflix.

"It’s great but I wish they’d stopped at the end of the first series", he said. "They absolutely must not move on to the younger generation".
